I have a sample app where I want to draw images with alpha channels so overlapping images will show the image underneath. No matter what I do, I can't get that to work. If I query the hasalphachannel property, it responds that the image has an alpha channel.
I am using a canvas with a picture buffer to draw the images inside a larger canvas., as per Eugine Dakin's ebook on how to use a canvas.
Mac OSX 10.12.6

All assistance appreciated. This is doing my head in.
